corporation of France Application February 19, 1938, Serial No. 181,533In France February 26, 1937 7 Claims.` (Cl. 10S-23) `My inventionrelates to improvements in those known roofs constituted by curved sheetiron or metal covers arranged adjacent or apart one with reference tothe other so as to form the 6 covering means proper.

My invention consists chiefly in arranging v arches in the longitudinaldirection of the covers, said arches being constituted for instance bybox girders for which the covers form tie-rods.

Preferably the covers are hung, at intermediary points of their lengths,to the arches through suitable ropes, chains or the like.

Although I may provide for each cover an arch for which said cover actsas a tie rod, it is prefer- 15 able to provide one arch for severalcovers. The arches are then interconnected at their ends through curvessuch as parabolas, for distributing the stresses and these curves areconnected with the ends of the covers through suitable girders.

Similarly for the transverse suspension, two

adjacent arches are connected through curves such as parabolas forinstance, arranged in transverse vertical planes and to which thesuspension means are connected. 25 The arrangement according to myinvention allows the execution of covering means of considerable spanwhile of reduced weight and the arches of which exert no thrust on thewalls or supporting posts. l

I have described hereinbelow by way of example a form of execution of myinvention.

In the accompanying drawings:

Fig. 1 is a diagrammatic perspective View of the said form of executionof the covering means.

Fig. 2 is an end View thereof.

Fig. 3 is a plan of the same covering.

Figures 4, and 6 are cross-sections of one bay between two consecutivearches made respectively by planes AA', BB and CC" of Fig. 3.

40 The roof of covering means comprises a series of metal covers ladjacent or very near one another and connected through butt straps l0for the ow of rain water and the like.

Said covers l may resist to a rather consider- 45 able longitudinaltraction but owing to their length they could not by themselves remainrigidly rectilinear and their own weight would cause them to benddownwards; it is thus necessary to support them at intermediate points.

To this end, arches 2 are provided above said covers, say, asrepresented on the drawings one arch for six rows of covers; said archesbeing of any convenient form, say constituted by box girders. The coversI act as rods for said arches, 56 and in order of distributing thethrust stresses exerted by said arches between all the rows of coversl,the arches 2 are connected transversely by braces 3, generally shaped asparabolas and are connected by means of stays 4 to the ends of thecovers. 5

Struts 8 may be inserted between adjacent arches for stiffening thewhole arrangement.

In order to maintain the covers at intermediate points of their length,the arches 2 are further connected to one another by curved members 5disposed in vertical planes, say under the struts 8, and constituted byropes, chains, girders or the like, said members 5 being connected tothe arch girders and to the covers by stays 6 of any convenient form. 15

The whole is supported by posts 1, walls or the like.

What I claim is:

1. Covering means for buildings, sheds and the like comprising aplurality of transversely curved covering elements lying parallel toeach other and arches extending longitudinally throughout the length ofsaid elements and of which said elements form the tie-rods.

2. Covering means for buildings, sheds and the like comprising aplurality of transversely curved covering elements lying parallel toeach other, arches extending longitudinally throughout the length ofsaid elements and for which said elements form tie-rods and means forsuspending the covering elements at intermediatev points of their lengthfrom the arches.

3. Covering means for buildings, sheds and the like comprising aplurality of groups of transversely curved covering. elements lyingparallel to each other, an arch for each group of elements extendingthroughout the length of said elements, the elements of each groupforming a tie-rod for the arches to either side of them, curved membersconnecting transversely the cor` responding ends of each two adjacentarches and stress-transmitting means inserted between said curvedmembers and the outer end of different covering elements.`

4. Covering means for buildings, sheds and the like comprising aplurality of Ygroups of transversely curved covering elements lyingparallel to each other, an arch-shaped box girder for each group ofelements extending throughout the length of said elements, the elementsof each group forming a tie-rod `for the arch-shaped girders to eitherside thereof, curved members connecting transversely the correspondingends of each two adjacent box girders and stresstransmitting meansinserted between said curved 55 y including a curved member connectingsaid.vl

arches and vertical suspending elements between said curved member andthe underlying coverying elements.
